I've been following a thread on the odd75 forum about OD&D treasure types, their max/average values, and their meanings in terms of contents and associated monsters. There's a little disagreement over something as basic as the relative total values of the different treasure types.
I've done some work on OD&D treasure type values before. The average and relative values should be pretty accurate, unless I've screwed up something. Download the Python script if you want a look at how I got these figures.
